Self-Managed Enterprise Edition

Self-Managed Enterprise Edition provides on-premises deployment with:

• Full control over your deployment

• Enterprise integrations (LDAP, SSO)

• Custom security policies and compliance

• All SaaS features in feature parity

Limitations

Chaos Engineering on Self-Managed Enterprise Edition has the following limitations compared to SaaS:

• Harness Enterprise ChaosHub is not connected by default

  • Contact Harness Support for access to the Enterprise ChaosHub

  • Git-based custom ChaosHubs are no longer supported. Use Templates to manage reusable chaos artifacts.

• Harness AI for CE

Supported Platforms

All platforms and fault categories supported in Harness SaaS are also supported in Self-Managed Enterprise Edition.

For more information about deployment, go to Self-Managed Enterprise Edition and CE on SMP.

Self-Managed Enterprise Edition in Offline Environments

Self-Managed Enterprise Edition in Offline Environments provides:

• Completely isolated from external networks

• Air-gapped deployment support

• All enterprise features available

• Custom security policies and compliance

Requirements

• Templates integration required for fault templates (Git-based custom ChaosHubs are no longer supported)

• Contact support for Enterprise ChaosHub access in offline environments

Supported Platforms

All CE features and platforms supported in Self-Managed Enterprise Edition are also supported in offline environments.
